Generic control planes and authorization at Upbound
- Cedar Policy joins the CNCF! 🚀 The cloud native community can now rely on a fast, safe, expressive, analyzable and formally verified authorization library when implementing access control🔓 This is a game-changer for implementing ACLs both safely & quickly aws.amazon.com/blogs/openso...
- This feels very similar to when I first saw Kubernetes more than 10 years ago. A project with the potential to transform an entire industry, with creators that have been facing these problems for a long time, and with already many prior iterations experience is drawn from.
- I gave a quote for the launch blog post as follows: “What I appreciate the most about Cedar is the deep knowledge that is encoded into why it works the way it works… the careful balance between expressiveness and analyzability.”
- Want to know how it could be used in the Kubernetes ecosystem? Check out github.com/upbound/kube... on Github and my talks on the Cedar at Speakerdeck: speakerdeck.com/luxas
